What is real-time data?

Your opportunities don’t last forever. Delaying a response and acting outside of a narrow time window significantly reduces the chances of success.
Acting on data in real-time is about immediate versus delayed. Fast versus slow. Now versus later.

Real-time data is about...

It’s about taking action right now.

In today’s data-driven world, real-time data entails meeting a business service-level agreement (SLA) with a narrow time window. Real-time is important because meeting the SLA creates business value.

Taking action the moment an opportunity presents itself, as opposed to after the fact, is where true value lies.

The best outcomes occur when we take action…

  • while the customer is banking
  • when the customer is shopping
  • during a fraudulent event
  • before a process breaks
  • when a patient needs attention, etc.

Faster than the speed of write.

Writes are slow. So why are you waiting to write to your database before acting on your data? In today’s on-demand world, immediacy is the expectation, not the exception.

Others claim to deliver real-time while waiting on databases and/or other services, causing lag and processing data after the event and missing out on real-time benefits. With Hazelcast, there’s no waiting on the write to the database.

Real-time responsiveness is often seen as an advantage with a sliding-scale tradeoff – the more real-time you have, the more resources you invested. But that’s no longer true because, with the right technologies, you can get real-time responsiveness with the same — or even less — of the resources that you need with traditional systems that make your stakeholders wait.

How does real-time data apply to you?

Most things in your life are in real-time, and these are things we naturally accept, like weather changes, stock price fluctuations, or emergency phone calls.

These are just a few examples where businesses can get value by delivering immediate responses to recent events:
